1.Whether, dairy is good or bad, still remain subjective. Dairy commonly known to offer many nutritional benefits, but it is not absolutely essential for maintaining overall health and well-being. In ancient times, when survival was challenged by harsh weather conditions, humans began consuming raw animal milk due to a scarcity of food. As these populations migrated from one geographical region to another, they gradually developed genes that allowed for lactose tolerance. This is how dairy became incorporated into the human diet. Today, many individuals may find dairy consumption uncomfortable.
2.Research has shown that though dairy is a good source of protein and calcium, it is not mandatory that without them, you can be deficient in this nutritional benefit. Having a regular balanced diet which is rich in pulses, leafy vegetables, and nuts can provide you with a better source of protein, calcium and loads of other nutrients than depending on dairy products. Though milk has been considered as wholesome food for both children and adults and is consumed throughout the millennia, many studies have shown cases of lactose intolerance and health risks to individuals through dairy. So, if you are not tolerant of dairy, it is important to avoid it, as there are plenty of other food sources which can provide the same nutrients.
3. Lactose intolerance: People who are lactose intolerant lack the enzyme lactase, which breaks down the sugar in milk. So, such individuals suffer from digestive distress and have different symptoms after consuming milk and dairy products. About 65% of the world’s population suffers from lactose intolerance. Lactose is found in almost the same amount in both A1 and A2 milk. So, people with lactose intolerance should avoid both A1and A2 milk. People with lactose intolerance may suffer from symptoms :
• Gas.
• Bloating.
• Stomach pain.
• Vomiting.
• Diarrhoea.
4.Studies show lactose intolerance is mainly due to gut sensitivity and lactose malabsorption. Most of the varieties of milk and milk products contain lactose, such as cow, goat,buffalo or sheep. Again, fresh milk, curd, and cream contain more lactose than cheeses. Lactose in dairy is used in many other products like processed food, biscuits, cookies, soups,snacks, and dressings. Therefore, if you are sensitive to lactose, all these food items can cause trouble when consumed. People need to read the labels of ingredients while consuming such products. Nowadays, many dairy products are made with the lactose being removed, such as some cheeses, lactose free milk, yogurt.
5.Allergies: Allergy to milk or dairy products can appear as early as childhood, wherein there may be mild to severe symptoms on consuming them. This is an atypical immune response resulting in various symptoms. Sometimes, it is life-threatening, which is known as an anaphylactic reaction.But, fortunately, with growing age, most of the time, the allergy disappears and dairy can be consumed without difficulty. In some individuals, the allergy can continue lifelong. Cow’s milk contains an allergen which triggers an immune response. But, some people may be allergic to other milks too, like sheep, goat or buffalo. Milk allergy is caused by milk proteins like casein and whey. Symptoms can be:
• Tightness of throat
• Swelling of the tongue
• Hives
• Stomach pain
• Vomiting, diarrhoea
• Persistent, cough, dizziness.
6.Inflammation: Though dairy may not be related to inflammation in most people. But studies do suggest that some people may be sensitive to beta-casein A1 protein found in most of the cow’s milk, which is connected to systemic inflammation. Long-term consumption of dairy is found to have a lowered anti-inflammatory effect in the body in those who have pre-existing conditions, metabolic abnormalities and are overweight. Some studies showed that milk processing causes changes in the basic components of milk, which can trigger inflammation in some individuals.Different small studies showed that raw milk consumption, due to its vast microbiota, increased the release of cytokines, which had a pro-inflammatory response. Again, UHT, homogenised high-temperature milk also showed pro-inflammatory cytokine release production both before and after digestion. Therefore, dairy can be inflammatory in some individuals depending upon some pre-existing conditions of autoimmune, metabolic and degenerative chronic conditions. Observation is important to pinpoint the type of food which can trigger an inflammatory response.
7.Several types of milk are available in the grocery aisle of a supermarket, including whole milk, low-fat milk and skimmed milk. Apart from this, several varieties of milk and dairy products of different sources like cows, buffalo, sheep and goat are available. Organic milk and grass-fed milk, which are anyway organic, do show a higher amount of Omega-3 than regular milk. Saturated fat contained in milk previously did show a relation to a higher risk of cardiovascular disease and stroke. But recent studies did not show direct evidence of this correlation. In terms of calories, Skim milk can be a better choice, which is loaded with vitamins, minerals, calcium and fewer calories.
8.Calcium absorption: Though in children and infants, calcium is absorbed about 50-60% from milk. But, as age increases, calcium absorption starts declining. It decreases about 25% as age increases and continues to decline. So, calcium from milk sources hold no significant for maintaining bone health. Chronic conditions like osteoarthritis and osteoporosis appear as age advances due to calcium malabsorption. So, to optimise calcium intake, other calcium rich food, calcium supplements should be taken to strengthen bone and muscles.
9.Commercial milk, mostly in Western countries, is produced by a breed of cows (Holstein, British Shorthorn, Friesian) whose milk contains A1 beta-casein. Research shows that A1 casein is difficult to digest and may create digestive issues in some individuals. A2 beta-casein milk protein are found in breeds of cows like the Indian breed, Guernsey, Jersey, which is much lighter and healthier for gut health. Most regular commercial milk contains both A1 and A2 beta-casein, while A2 milk marketed contains only A2 beta-casein.
A small amount of oestrogen naturally found in milk has no harmful effect on humans. Commercial farms inject synthetic growth hormone into cows for fast growth. Exogenous oestrogen is injected into pregnant and lactating cows to increase milk production. This is also done in other animals like buffalo, sheep and goats. Studies showed that such commercial milk consumption can lead to gonadotropin suppression in men and early sexual maturation in prepubertal children. But, most cheeses do contain medium chain triglycerides, which are healthy for the body and mostly the hormonal effect is gone.
10.Dairy as a food type is a range of heterogeneous items, ranging from different varieties of milk and milk products from different sources. Though dairy continues to be an easy and common source of nutritional benefits, many studies do highlight the harmful effects of dairy on human health. Therefore, some people have considered going dairy-free. In general, dairy is not necessary for overall health and wellbeing; there are other ample sources of food items like plant-based milk, green leafy vegetables, legumes, nuts and seeds, quinoa and oats to maintain health and wellness.
